from No-Nonsense Psychiatry Practical Mental Health Lets Talk Together · host markjohnskay
Your face has two distinct "wiring" systems. In this episode of No Nonsense Psychiatry, we explore the conflict between the Pyramidal (Voluntary) Tract and the Extrapyramidal (Involuntary) Tract. We look at why it’s physically impossible to suppress a micro-expression when the amygdala is triggered. We provide three actionable cues to help you spot the "Big Seven" universal emotions—Fear, Anger, Disgust, Sadness, Enjoyment, Surprise, and Contempt—in yourself and others.
